About this Plan

Zilch Mark 40 (Mark 40 Zilch). Control line stunt model, for .15 to .25 engines. Plan includes full build instructions.

Quote: "Building and Flying Instructions.

The Mark '40' Zilch Stunt Controline design is an extremely easy model to assemble, and features all balsa construction, with 'machine milled' leading and trailing edges. In the air it is a top performer, rugged and reliable.

Familiarize yourself with the plan and kit contents as the first step. Remove all parts from the die-cut sheets, trimming or sanding if necessary. Most parts are easy to recognize, and the remaining few which might puzzle you will position themselves as you proceed.

Start construction with the tail assembly. Sand the die-cut parts smooth and bevel edges as seen in the side view. Locate elevator horn, and hinge elevator to the stabilizer with the pinked tape. Keep cement off hinge edge for best rusults.

Wing. Cement the upper and lower leading edge halves together. Use a number of die-cut ribs as temporary spacers while the cement is drying. In the meantime attach the bellcrank to the laminated 1/4 in plywood deck. Install the leadout wires in the bellcrank. (These wires are purchased separatly for the basic kit. Use .021 stranded wire or .028 solid wire, about 24 in long. See sketch on how to fasten lead-outs to the bellcrank..."

This is an Uncle Willies plan.

Direct submission to Outerzone.

Note this plan does not show the full wing layout.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
